The Claim

Selenoprotein expression in the mouse liver increases dramatically after birth, with Selenop rising over 500-fold from embryonic day 12.5 to postnatal day 30 and Dio1 increasing more than 800-fold from postnatal day 7 to postnatal day 30, reflecting the liver’s central role in selenium transport and thyroid hormone activation during postnatal metabolic maturation.

Description
1 study reviewed
In plain English

In mice, the levels of two liver proteins, Selenop and Dio1, increase sharply after birth, with Selenop rising more than 500 times and Dio1 rising more than 800 times during the first month of life, coinciding with the liver’s established function in selenium transport and thyroid hormone processing.

See the scientific wording

Selenoprotein expression in the mouse liver increases dramatically after birth, with Selenop rising over 500-fold from E12.5 to P30 and Dio1 increasing more than 800-fold from P7 to P30, reflecting the liver’s central role in selenium transport and thyroid hormone activation during postnatal metabolic maturation.

Why this might work

After birth, the liver starts making much more of two key proteins: one that carries selenium to other organs, and another that activates thyroid hormones. The increase in selenium lets the liver make more of these proteins, which in turn fuels the body’s shift to using oxygen for energy and supports growth by boosting metabolism.

    After baby mice are born, their livers start making a lot more of two special proteins that help move selenium around the body and activate thyroid hormones — exactly what the claim says. This happens because the babies need more energy and can’t rely on their mom anymore.
